Shoaie, Srosh (author)DIMITRI is a tool that has been developed for monitoring the radiometric performance of optical instruments onboard Earth observation satellites. It includes a reflectance model through which a calibration coefficient is computed which is used for performance monitoring. In this thesis, the uncertainty that is associated with this coefficient is...master thesis 2017

Woofenden, George (author)Current Port of Rotterdam procedure is to define the nautical depth based on the density of a fluid-mud layer, that settles at the bottom of the port. Rheological parameters could be an improved indicator for nautical depth and decrease the frequency and cost of dredging. I investigate the use of reflected seismic waves to derive in situ...master thesis 2017

Caichac Avilés, Daniel (author)Numerical process-based morphodynamic models are widespread in coastal engineering practice and have become the new standard when it comes to assessing the impact of natural or man-made structures on coastal environments. The most common practice among engineers is to focus on a single spatial and time scale, which means either neglecting...master thesis 2017

Dwarkasing, Arvind (author)Ion exchange membranes (IEMs) are used to selectively transport ions between two solutions. Most membranes are not selective to certain ion species. This study investigates the possibility of increasing phosphate selectivity (in the form of H2PO4 – ) of anion exchange membranes (AEM) by modifying commercial AEMs with a Layer-by-Layer (LbL)...master thesis 2017

Boon, Inge (author)This graduation report was commissioned by NS International to determine the wants and needs of travellers while travelling internationally by train, but also to identify the barriers which prevent travellers from actually using the train for cross-border travel in order to design a service proposition. This proposition will contribute to a...master thesis 2017

de Looij, Ivo (author)The SkelEx exoskeleton is a non-linear spring-based passive upper body exoskeleton that has the goal to compensate the weight of the wearer's arms. Bending of three stacked non-linear springs transfers force from the hips of the wearer to the back of the upper arm. The amount of bending of the springs is a function of the geometry of the...master thesis 2017

Anderson, M.C. (author)In the 26 years since the first offshore wind farm was installed in Vindeby, Denmark, the offshore wind industry has undergone remarkable growth. Recently, this growth has accelerated, advancing farms rapidly into deeper water and utilizing larger turbines. As offshore wind farm developers continue to look towards heavier, higher capacity...master thesis 2017

Gootjes, Didier (author)Small-scale 3D-printing has become a common appearance. Today there are many companies specialized in selling and designing small-scale 3D-printers . Applications range from creating custom-made toys to creating spare parts for the 3D-printer itself as well as medical applications such as skull parts, knee replacements and hip replacements. The...master thesis 2017

Manzoor, Qasim (author)The Blade Element Momentum (BEM) method is a widely used model for rotor performance and aeroelastic calculations but it has assumptions in its formulation which limit its accuracy. The theoretical background of these limitations has been studied and an improvement in the form of the Near Wake Model (NWM) has been identified. The model adds near...master thesis 2017

Rivera Arreba, Irene (author)Floating wind turbines (FWTs) are proposed as a method to harness the significant wind energy resource in deep water. International research efforts have led to the development of coupled numerical global analysis tools for FWTs in order to understand their behavior under wind and wave actions. The hydrodynamic models in such tools are typically...master thesis 2017

Hinkofer, Thomas (author)With an increased demand for renewable energy sources, geothermal developments have moved into the spotlight, including sedimentary structures. In the western part of the Netherlands, cretaceous sandstone bodies are already in use for the geothermal energy production. However, these reservoirs are generally producing water at temperatures less...master thesis 2017

Smeets, Martijn (author)As part of the ESA mission to Jupiter and Ganymede carried out by the Jupiter Icy Moons Explorer (JUICE) spacecraft, the Ganymede Laser Altimeter (GALA) will determine the topography and detect Ganymede’s tidal degree-2 signal in order to investigate the existence of a subsurface ocean and constrain its thickness. To deliver successful...master thesis 2017

Aramburo Velez, Daniel (author)The Dutch Government is aiming for a CO2 neutral energy supply in 2050; this requires a transition from using energy from fossil fuels to using renewable energy sources. Decline in oil production in the Netherlands occurs in an epoch with an increased interest in geothermal heat production as an alternative source of energy. In the present study...master thesis 2017

Appiah, Sevyllen (author)Resonant motions of a combined wind and wave concept (STC) in waves may induce significant loads in the structural components (such as wind turbine blades, nacelle or the interface between the spar and the torus). One type of resonant motions is related to the so-called Mathieu instability. For the STC under the survival mode where the torus is...master thesis 2017

Li, Ruyu (author)A driver with high power factor, high efficiency and safety isolation are more attractive in the lighting application. Flyback is an ideal choice to be the power factor stage in LED driver. But one of the most difficulty in flyback topology is the energy stored in its leakage inductance. This part of the energy will introduce very high voltage...master thesis 2017

Anggrit Dewangkara Yudha Pinangkis, Anggrit (author)Wireless data traffic is growing rapidly as the number of mobile devices increase and video contents become more popular. As 2.4\,GHz and 5\,GHz band communications only provide limited bandwidth, these frequency bands cannot support the demand of ultra-high data rate. Millimeter-wave (mmWave) communications promise massive available bandwidth...master thesis 2017
